Vision improvement training instrument

Abstract

The invention relates to the technical field of vision improvement and discloses a vision improvement training instrument. The vision improvement training instrument comprises a box, a panel, a tyingband as well as a pupil distance adjusting device and a movable zoom device which are mounted in the box, wherein a front vision window and a back vision window are arranged on front and back sides ofthe box respectively. External replaceable lenses are designed in the position of the back vision window, preset pupil distance adjusting numerical values are arranged above the panel of the back vision window, and intensive magnetic sheets are mounted in the position, close to eye acupoints, of the panel. During use of the vision improvement training instrument, the focal length of eyes of a user can be expanded far continuously, so that non-emmetropia is induced to see a target object clearly and turn into emmetropia, the focusing, watching and following capacity of eyes can be enhanced, the effect of improving vision can be realized, and the training instrument is applicable to preventing, controlling and improving myopia, astigmatism, amblyopia, anisometropia and asthenopia.

Description

technical field [0001] The invention relates to the technical field of vision improvement, in particular to a vision improvement training instrument. Background technique [0002] Due to changes in learning and working methods in modern society, the myopia population is increasing day by day, especially the incidence of myopia among teenagers is increasing year by year and remains high. There are various reasons for the formation and development of myopia, but it is undeniable that long-term short-distance eye use is one of the main factors for the continuous generation and development of myopia. Long-term close-distance eye use will cause long-term tension and contraction of the ciliary muscle. Then spasm occurs, which leads to the occurrence of pseudomyopia. If there is no intervention and improvement at this stage, it will gradually evolve into true myopia. At present, the control methods for myopia usually include orthokeratology lenses, optical glasses, massage, and eq...

AI Technical Summary

Problems solved by technology

At present, the control methods for myopia usually include orthokeratology lenses, optical glasses, massage, and equipment, but the control effect of the glasses itself is limited. The key population of myopia is teenagers and they have heavy schoolwork. In addition, the design principles of such equipment are not targeted. , the training method is boring or inconvenient to use, which cannot attract students' interest, resulting in limited control effect and durability
